Question

急！用c语言编写程序计算n的阶乘，能运行且简单的程序

Answer 1

/*该程序调式通过*/
#include <stdio.h>

#define n 5 /*该值自定*/
main()
{
int cnt=n,i=1;
do
{
i*=cnt;
}while(--cnt);
printf("%d\n",i);
getch();
}

Answer 2

#include<stdio.h>

int f(int i)
{ while(i!=1)
return i*f(i-1);
}

int main()
{ int n;
printf("please input n:");
scanf("%d",&n);

printf("n!=%d",f(n));
}

Answer 3

#include <stdio.h>

#include <conio.h>

int main(void)

{

int n,i; 

int sum=1;

printf("请输入n:");

scanf("%d",&n);

for(i=1;i<=n;i++)

{

sum=sum*i;

}

printf("n!=%d\n",sum);

getch();

return 0;

}

Answer 4

for(;n>0;x--)
{
count*=n;
}
